I have to switch the computer of at the mains. When i came to switch it back on i get an error bootmgr is missing, so i put the windows 7 dvd in drive and windows starts.

 

I have three hard drives two internal and 1 external, what the pc is doing is looking on the HDD that does not have Windows on (J = Disk 0) but windows is on (C = Disk 1).

 

How can i change these around so that i do not need the DVD in the drive all the time.

 

I think i can use Disk Management, but i have forget how to do this

Start your computer and press F8 to access the Advanced Boot Options menu. Select Repair Your Computer.

 

Select the Command Prompt option.

 

Type bootrec /rebuildbcd and press Enter.

 

The scan should identify your correct Windows installation and you will be asked to Add installation to boot list?  Type Y and press Enter.

 

You should see the message The operation completed successfully.

 

Restart your computer.
